Morphology

telephone + jack

The meaning 'a socket for plugging a telephone' is directly derivable from combining 'telephone' (the device) with 'jack' (a socket/plug receptacle). This is a transparent compound following common English noun-compounding patterns and has clear parallels in other languages, so a B1 learner who knows both constituents will readily infer the meaning.

Etymology

Telephone jack comes from the simple image of a small wall socket where the plug from the telephone fits into the jack. When the plug is 'plugged in', the phone is 'connected' to the network, so the phrase means the socket to 'plug a telephone into'.
